17 Plumbing Myths That Don’t Make Sense and the Truth Behind Them
Tim Michael
Plumbing is one of those things we tend to take for granted—until something goes wrong. Over the years, I’ve encountered all sorts of plumbing myths. Some of these misconceptions can lead to expensive fixes or even damage to your home.
Today, I’ll dispel some of the most common myths about plumbing. Let’s dive in and make sure you have the right information to keep your home’s plumbing in tip-top shape.
You’ve probably seen “flushable” wipes on store shelves, and they sound convenient, right? Here’s the truth: these wipes don’t break down like toilet paper. Even though they might go down the toilet, they can pile up in your pipes and eventually clog your system. Over time, these clogs can lead to sewer backups, which are a nightmare to deal with.
As a plumber, I’ve lost count of how many times I’ve been called to fix a pipe clogged with “flushable” wipes. Trust me, pulling out a giant wad of wipes from someone’s plumbing isn’t pretty. Instead of relying on marketing labels, stick to using toilet paper only. If you need wipes for cleaning, toss them in the trash after use. It’s a small habit that can save you a lot of trouble (and money).
I hear this one a lot: “Just pour some hot water down the drain to get rid of grease.” It sounds logical, but it doesn’t work the way people think. Sure, the hot water melts the grease initially, but as it moves through the pipes and cools, the grease hardens again. Over time, this can cause significant blockages.
In my experience, grease is one of the main culprits behind clogged kitchen drains. What is the best way to deal with it? Don’t let it go down the drain in the first place. Pour leftover grease into a container and throw it in the trash once it solidifies. If you already have a clogged drain, skip the DIY tricks and call a plumber for proper cleaning.
A dripping tap might seem like a small issue, but it’s anything but harmless. Did you know that a single leaky faucet can waste thousands of litres of water over a year? That’s not just bad for the environment—it’s also bad for your wallet when the water bill arrives.
Fixing a leaky faucet is usually quick and inexpensive. In most cases, it’s caused by a worn-out washer or a faulty valve. I’ve handled plenty of these repairs, and they’re often straightforward. Ignoring the problem, however, can lead to bigger issues like rusted fixtures or water damage. Don’t wait—fix that drip before it becomes a flood of problems.
There’s a lot of pride in handling home repairs yourself, but plumbing is only sometimes a DIY-friendly task. While you might manage to unclog a toilet or fix a dripping tap, some jobs need professional tools and know-how. For example, replacing a burst pipe or repairing a gas line is something you should only attempt with training.
I’ve seen too many DIY jobs go wrong, turning a small issue into a big mess. One client tried to repair their own water heater, only to end up flooding their garage. Another accidentally broke a pipe while trying to clear a clog, causing water to gush into their home. When in doubt, call a professional. You’ll save time, money, and stress in the long run.
This old-school “hack” has been floating around for years, but it’s more trouble than it’s worth. The idea is that a brick displaces water in the toilet tank, reducing the amount used per flush. While it might save a bit of water, it can also cause problems.
Over time, bricks can crumble and damage the tank’s components. I’ve replaced many toilet parts ruined by this so-called money-saving trick. Instead, consider upgrading to a water-efficient toilet. Modern models use less water per flush without compromising performance, and they’re a much safer choice for your plumbing system.
When your sink or tub backs up, it’s tempting to grab a bottle of chemical drain cleaner. They’re cheap, easy to find, and promise fast results. But what they don’t tell you is that these cleaners can do more harm than good.
The harsh chemicals in these products can eat away at your pipes, especially if you use them frequently. I’ve seen pipes corroded to the point of needing replacement because of overuse. Instead of risking long-term damage, try a plunger or a plumber’s snake to clear clogs. For stubborn blockages, call a plumber who can assess the situation without damaging your plumbing.
Most people only think about their water heater once it stops working, but regular maintenance is crucial to keep it running efficiently. Over time, sediment builds up inside the tank, reducing its ability to heat water and increasing energy costs.
I recommend flushing your water heater at least once a year to remove this sediment. It’s a straightforward process that can extend the lifespan of your heater and save you money on energy bills. If you’re not comfortable doing it yourself, a plumber can handle it for you during a routine inspection.

A lot of it comes down to misinformation shared by word of mouth or online. It’s easy to believe a quick fix or hack, especially when it’s cheaper than hiring a professional. But as someone who’s been in the plumbing trade for years, I can tell you that shortcuts often lead to bigger problems.
